It is generally understood that automatic vehicle transmissions include shifters that are held in a park mode until an ignition of a vehicle is on and a brake pedal of the vehicle is depressed. To hold the shifter in the park mode it is common for a solenoid actuator to mechanically displace a blocking member or cam. However, the actuation of solenoids in the present state of the art can result in distracting noise that may be associated with inferior quality and may lead to deterioration as a result of the associated friction.
